WI ND OW Filed Maron 30, 1933 Patented Dec. 4, 1934 UNITED STATES PATENT OFFICE 8 Claims.

My invention relates to a window of a type illustrated in my United States Patent No. 821,353 of May 22, 1906, for Tight and noiseless casements for swinging closures.` U

An object and feature of my invention is a pivoted sash in which resilient weather strips form a seal or closure on the window frame at all sides of the window, when such window is closed. 'l'hat is presuming that the sash is pivoted at the sill and sofiit of a window frame, the sash when closed on account of having the weather strip mounted on the sash will form a tight closure against not` an only the soit and the sill but the two side lambs of the window frame.

Another object and feature of my invention is in a pivoted type of sash to provide a resilient weather strip on the sides Ahaving the pivots so that these weather strips will contact with flat surfaces in which the pivots are mounted to turn, thus if the sash is pivoted inthe somt and sill of a window, the resilient weather strip engaging the somt and the sill holds the window at any desired degree of opening without any other holding or adjusting features.

Another further object and feature of my invention is the employment of a means for adjusting the projection of the resilient weather strip from the frame of the sash. This is obtained by the construction of a sash formed of two separable 0 parts which engage the resilient strip and also by its employment in vehicles is expansion springs which force the -weather strip, which 'is preferably rubber, outwardly.

Another feature of my invention as relates to the mounting of the sash in-such a manner that when the vehicle is proceeding in a forward direction so that the general flow of air is along thevehicle, the sash may be set to create a partial vacuum on the outside of the vehicle so that air is sucked from the inside to the outside.

In this connection vopposite directions.

a reverse curve or Figniy is a section on the line 4 4 of Figure 3 in the direction of the arrows through one of the pintles.

Fig. 5 is an edge view of the expansion spring used to press theweather strip outwardly, taken on the section line 5-'5 of Figure 3 in the direction of the arrow Fig. 6 is a transverse section through a modified sash frame showing the man ner of holding the rubber weather strip.

Referring first to the construction of Figures 3 d 4, I illustrate a window frame 11 which may be considered as having a sill 12. This has a iiat upper surface 13. The somt is the same and also has a nat lower surface. The two side jambs 14 of the window have center sections 15 formed on a convex curve. The outer portions 16 may have any type of ysuitable molded shape extending to the outside and inside edge of the window jamb. The sill and somt are provided with pintle sockets 17 in which there is preferably inserted a bushing 18 which may be of hard rubber or some other material which will not rattle.

'Ihe saine type of sash is shown substantially in all the figures, the sash ofl Figure 2 being substantially the same as that oi' Figures 3 'and'4. 'I'he window sash 19 employs a metalframe 20l which holds the glass 21. 'Ihe metal frame is shown as having similar inside and outside frame bars 22. 'I'hese frame bars each have an inward'- ly pressed section' 23 through which are screws 24 spaced longitudinally of Vthe frame.

n outside jaws 27. The weather strip is illustrated as formed of two flat strips of rubber held tightly together by the two Jaws.

'Ihe pintles 28 each fit in a bushing 18. A pintle plate 29 forms an extension of the pintle and is secured to the side bars of the frame by screws 30 as illustrated in Figure 2. Each pintle plate is illustrated as having a shoulder 31 which is held spaced from the sill surface and the soiiit surface by the projecting rubber weather strip on the pintle sides of the frame.

In order that the weather strip may be pressed outwardly to facilitate adjustment, a compression spring assembly 32 is fitted between the jaw portions o1' the frame bars carrying the weather strip. This and 34 which are held spaced apart by a Wave formed spring 35. 'I'his latter spring is resilient and tends to press the strips 33 and 34 apart;

spring assembly has two strips 33 the frame by being secured to one of the frame Y bar assemblies, thus facilitating the opening and! closing of a window.

'I'he window is operated and functions as follows. On account of the pintles being through iiat surfaces, for instance at the of a sash, the weather strips on the sides of the sash having the pintles will bear against the fiat surfaces of the frame. Thus if the sill and -the soit of the window is at and the pivotsare in the soiiit and the sill, the rubber weather strip engaging these fiat surfaces'will hold .the win.- dow in any desired degree of opening. The window may be opened by ing on eithersideedge towards a jamb of the window. This will swing the sash 'into anA angu'. lar position such as shownvin Figure Presuming, therefore, that there is a movement of-,air on the outside in the direction of the arrow 38', which would-occur'if the sash were on a vehicle moving in a direction to cause such airpull, then a partial vacuum will be created outside. of the` sash and cause` an outward flow of airin vthe direction of the arrows 39 and 40. One'of. the objects of having the. jambs` formed convex.- as

shown at 15, .is that a slight` arcuate move-l ment of the sash will give a larger opening between the weather.v strip adjacent the jamb than if the jamb were made hat. vAlso on ac- ,count of thev pivotbeingoffset at one side from the rubber weather strip at. the pivoted portionsy there is a slight movement of translation aswell as an arcuate movement of the weather strip on f to thejamb. This movement is readily accommodated'zby the the sides of the sash infreference convex shape of the jambs and alsoby the resiliency of the weather-strip. f
